convert: keep branch switching merges with ancestors (issue3340) When running convert with a filemap, merge parents which are ancestors of other parents are ignored. This is hardly a problem when parents belong to the same branch, but the result could be confusing when named branches are involved. With: -o-a1-a2-a3... <- A \ \ b1-b2-b3...-m- <- B If all b* revisions are discarded, it is useful to preserve 'm' even if it is empty after filtering to record the branch switch. This patch makes filemap preserve "ancestor parents" if there is no "non-ancestor parent" on the same branch than the merge revision. Remarks: - I am not completely convinced by the reasons given above and those detailed by Matt in this thread: http://selenic.com/pipermail/mercurial-devel/2012-May/040627.html The properties we try to preserve are not clearly defined. That said, I know this patch already helped someone on IRC and the tests output look reasonable. - This is a new version of the original "convert: filemap must preserve fast-forward merges" patch. It has exactly the same output for 2 parents merges, the additional complexity is here to handle more than two parents.

revset: add "diff" field to "matching" keyword The new "diff" field lets you use the matching revset keyword to find revisions that apply the same change as the selected revisions. The match must be exact (i.e. same additions, same deletions, same modified lines and same change context, same file renames and copies). Two revisions matching their diff must also match their files. Thus, to match the diff much faster we will always check that the 'files' match first, and only then check that the 'diff' matches as well.

mq: defer command wrapping to extsetup (API) mq wraps all commands that are not in commands.norepo, which is now performed in this second phase of the extensions setup process. This goes against the current best practices on the wiki [1] as far as where command wrapping is performed, but follows it regarding where global options are injected. mq needs to be the first layer called when command dispatching in order to consistently retarget to the patch repo, regardless of the load order of the extensions. This means being the last to wrap the command table. Previously, 'hg <extdiff> --mq' would diff the main repo unless mq was enabled after extdiff.

revset: ensure we are reversing a list (issue3530)

test-keyword: adapt for Windows

tests: don't use dates before epoch in test-keyword.t Timezone offsets of less than a minute is not shown but can cause displayed dates to be before epoch start - and dates before epoch start is not shown correctly on Windows (see also 4d5b12a5517b). These 'negative' dates could be considered undefined behaviour so we don't care and swap the tests values for timestamp and timezone.

tests: make test-convert-bzr.t more stable The test would occasionally fail because datesort don't have sub-second granularity and thus can't sort commits made in the same second. The test is made more stable by adding 1 second of sleep to make sure the bzr commits are done with different timestamps.
